COVID, air hygiene and commercial purifiers - what you need to know

Installing suitable air purifiers at your workplace could form a key part of your COVID-19 risk-prevention strategy, helping to reduce the risk of the airborne transmission of small saliva particles which have been found by scientists to linger in the air for longer.

In our free webinar Clean the Air We Share, clean air ambassador Mike Booth draws on advice from world health bodies to discuss air purifiers and the role they could play in the ongoing management of COVID-19 in workplaces. In this post we break down some of his key points and take a look at AeraMax® Professional - the air hygiene solution we've selected to supply to our clients.

What does the science say about airborne virus transmission?

In an open letter published on 6 July, over 200 scientist implored health organisations to update the COVID-19 prevention recommendations to address the airborne transmission of small particles. They argued that risk prevention recommendations were focused heavily on transmission through physical contact and inhaling large particles (through coughing and sneezing), while neglecting the risk of inhalation through small particles, which carry through coughing, sneezing, talking, singing and breathing. The risk of smaller particles is that they are light enough to linger in the air for longer, even after the infected person has moved away.

According to the report, “Multiple studies have demonstrated beyond any reasonable doubt that viruses are released during exhalation, talking, and coughing in microdroplets small enough to remain aloft in air…posing a risk of exposure at distances beyond 1-2m from an infected individual.”

Signs point towards the need for suitable indoor air management

Cleaning surfaces, washing hands and keeping a safe distance from each other are all effective risk measures, but they don't protect us from the small particles of contaminated saliva that could be lingering in the air.

To tackle airborne transmission, we need to start looking at products designed to clean indoor air, known as air purifiers. However, not all solutions are suitable.

The Chartered Institute of Building Services (CIBSE) outlines the following recommendations for office air management:

  • Avoid air circulation, which moves air between spaces.
  • Increase ventilation by diluting the air - have system running all the time.
  • Warns against existing filtration improvements - you can end up doing more damage to existing systems, it's not a quick fix to simply install new parts.
  • Warns against UV-C sterilisation methods - there are multiple challenges to consider.
  • For a portable air cleaner to be effective it must have HEPA filter.

AeraMax® ticks all of the above boxes, and more. The technology incorporates several layers of filtration featuring a True HEPA filter with antimicrobial treatment, which captures 99.97% of airborne particles— as small as 0.3 microns.

Find the right model for the space you want to protect and have instant visual, real-time feedback on the room's air quality. Wall-mounted and aesthetically pleasing, AeraMax® will fit in discreetly to your office surroundings to help reduce the risk of viral contamination, and introduce broader benefits such as:
